81861-75-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81861-75-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,6 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81861-75:
(7*8)+(6*1)+(5*8)+(4*6)+(3*1)+(2*7)+(1*5)=148
148 % 10 = 8
So 81861-75-8 is a valid CAS Registry Number.

Synthesis of C2-elongated polyunsaturated fatty acids

Kuklev,Popkov,Kas'yanov,Akulin,Bezuglov

, p. 192 - 195 (2007/10/03)

The synthesis by a modified malonic ester procedure of C2-elongated polyunsaturated fatty acids from their natural precursors was described. Using the suggested Scheme 1, (7Z,11Z,14Z)-7,11,14-eicosatrienoic, (8Z,11Z,14Z,17Z)-8,11,14,17-eicosatetraenoic, (5Z,8Z,11Z,14Z,17Z)-5,8,11,14,17-eicosapentaenoic, (8Z,11Z,14Z,17Z)-8,11,14,17-docosatetraenoic, (7Z,10Z,13Z,16Z,19Z)-7,10,13,16,19-docosapentaenoic, and (6Z,9Z,12Z,15Z,18Z,21Z)-6,9,12,15,18,21-tetracosahexaenoic acids were synthesized. Their structures were confirmed by GC, UV, and MS data, which coincided with those of natural compounds. The target compounds were shown to be free from by-products, which could result from Z-E isomerization or migration of double bonds. The overall yields of the four-step synthesis of C2-elongated polyenoic acids were 25-30%.
